I have a Philips HD TV, a Samsung DVD Recorder, Bell Express Vu-PVR and a Sony wireless headset. I have everything working I (at least it appears to be ) except when I plug in the wireless headset, I either get sound on DVD only, Sound on TV only or both. Any suggestions on setup.

Sound on TV only should be OK as everything (DVD, SAT,. ) all go to TV.
The TV may have an audio out, and in Menu, be Fixed or Varible with volume control.
